2010: two-year-old season Danedream made her first appearance in June 2010, when she won a minor race at
Wissembourg by two and a half lengths. She was moved up to
Listed class a month later to finish third in the Oppenheim-Rennen at Köln. Sent to France for a race at Deauville she finished first, but was disqualified and placed third. In October she returned to France for the
Group One Critérium des Pouliches at
Longchamp. She started a 33/1 outsider and finished sixth of the eight runners behind
Misty For Me. Later in the same month she finished third in the
Preis der Winterkonigin on her final start of the year.
2011: three-year-old season On her three-year-old debut, Danedream was sent to
Milan for the Listed Premio Seregno over 1600m. She looked outpaced in the straight before staying on to finish fourth. On her next start, Danedream was moved up in distance to 2300m and gave the first indication of her true ability when running third against colts in the
Derby Italiano in Rome. Three weeks later in Milan she recorded her first important victory in the Group Two Oaks d'Italia, taking the lead 400m from the finish and pulling away from her opponents to win by six and a half lengths. Disappointment followed at
Saint-Cloud a month later, when she finished only fifth to Testosterone in a blanket finish to the
Prix de Malleret. Danedream returned to Germany for her next start and produced by far her best performance to date in the Grosser Preis von Berlin. After being held up early in the race she was sent into the lead by
Andrasch Starke 300m out and drew clear to win by five lengths from the 2010 German Horse of the Year Scalo, with the 2009 German Horse of the Year Night Magic in fourth. In September she confirmed her status as Germany's best racehorse by beating Night Magic by seven lengths in the Grosser Preis von Baden. The
Canadian International Stakes winner Joshua Tree was a further six lengths back in third and the
Deutsches Derby winner Waldpark finished last of the six runners. Despite two emphatic wins at Group One level she was not regarded as a major contender for the
Prix de l'Arc de Triomphe and started 20/1 outsider in the sixteen runner field. Starke settled the filly in the middle of the field before making his challenge in the straight. Danedream moved strongly through to take the lead from
St Nicholas Abbey and
Shareta 200m from the finish and was never in any danger of defeat, pulling away to win easily by five lengths from Shareta, with
Snow Fairy third and New Zealand-bred champion
So You Think fourth. Her winning time of 2:24.49 broke the course record set in 1997 by
Peintre Celebre. On 27 November Danedream started 2.3/1 favourite for the
Japan Cup at
Tokyo Racecourse, despite being drawn wide in stall 13. She was held up towards the rear of the field as the American entry Mission Approved set a steady pace. At the turn into the straight, Starke switched his filly to the wide outside and Danedream began to make progress. She was never able to reach the leaders however, and finished sixth of the sixteen runners behind the five-year-old mare
Buena Vista, beaten three and a half lengths. Schiergen felt that the filly had taken too much out of herself in the early stages as a result of her wide draw position. In March 2012, Danedream was elected
German Horse of the Year, receiving 90% of the public vote.
2012: four-year-old season Danedream made her first appearance of the season in the
Grosser Preis der Badischen Unternehmen at Baden-Baden on 20 May. Starting at odds of 2/5, she tracked the leaders before moving to the front 200m from the finish and winning by three quarters of a length from Ovambo Queen. On 24 June, Danedream started odd-on favourite for the
Grand Prix de Saint-Cloud but after briefly taking the lead, she was overtaken in the straight and finished last of the four runners behind Meandre. On July 21, Danedream was sent to contest Britain's most prestigious all-aged race, the King George VI and Queen Elizabeth Stakes at Ascot. The field of ten included the Group One winners
St Nicholas Abbey,
Dunaden,
Masked Marvel,
Nathaniel,
Deep Brillante and
Reliable Man. Starke tracked the leaders before making his challenge in the straight. In an extremely close finish, Danedream caught Nathaniel in the last stride to win by a nose. She became the first German horse to win the race and the first filly to win both the Arc and the King George. Danedream returned to Germany for her second Grosser Preis von Baden in September, in which her main rivals appeared to be the three-year-old colts Pastorius and Novellist who had finished first and second in the
Deutsches Derby. Reportedly unsuited by the slow early pace, Danedream took the lead in the straight and held the persistent challenge of Ovambo Queen to win by half a length, with Pastorius the same distance away in third. A week before Danedream was scheduled to run in her second Arc a horse at the
Cologne training centre tested positive for
equine infectious anaemia. Although Danedream was not affected by the disease, she was banned from traveling as all 300 horses at the centre were placed in
quarantine by the German agriculture department. ==Breeding==
